Heartworm disease and vaccines are currently some of the 'hottest' topics in Veterinary Medicine. Veterinary Medicine has exponentially exploded in knowledge, diagnostics, treatments, nutrition and behavioral understanding. These advances have allowed us to better understand our pets, the diseases that affect them and us, and allow them to live longer and happier lives. As little as 15 years ago it was rare to see dogs live past 12 or cats live past 15 years of age. Now, we commonly see dogs at or past the age of 15 and many indoor cats past the age of 20. Unfortunately, as quickly as we learn, so do the many viruses, bacteria and parasites that surround us each and every day.

Caledonia and the surrounding area (the communities between the lakes, as far west as Brantford and as far east as Grimsby) now have the highest incidence of heartworm disease in all of Canada for dogs (and we now suspect cats). We routinely find upwards of 40-50 infected dogs annually. However, we are only currently testing a small percentage of our pet population. Many dogs and wild life never receive heartworm testing or prevention and act as the reservoir for the disease.

We now know that over 50 different species of mosquitoes can harbor and spread the disease. Mosquitoes have been able to adapt well to our changing climate. It is not uncommon to find mosquitoes in our homes in November, unseasonably warm days in winter or even very early in the spring. These disease carrying insects can be found in firewood, camping equipment or even patio furniture in for winter storage.

Hookworms and roundworms are intestinal worms found in dogs, cats and many wildlife (raccoons, skunks, mice, birds etc.). In recent years, the spread of these parasites to humans (zoonosis) has become more of a problem. Children, elderly and the immunocompromised are the most susceptible. The increase in zoonotic spread is due to many factors; urbanization and a growing pet population being the largest factors. Sandboxes, parks and gardens can be extremely dangerous places. Even the indoor cat or a dog that does not leave home are at risk. Animals do not have the same hygiene as humans. We as owners go everywhere bringing home potential disease. Our pets lick our floors and shoes. Even catching a mouse or a bat in the house may result in serious illness for the pet and potentially the owner.

Simple monthly prevention with products such as Interceptor (or other products) year round may be the key to controlling these diseases. The cost of using these products outside typical flea and tick season is very cost effective. Depending on the weight of your pet, the cost may be as little as a few dollars a month, a small price to pay to know that your pet and family are protected.
